How do you recognize a liberal?

Liberals are just people who are actively fighting for social justice, peace, and the environment. Unfortunately they have mostly been replaced by progressives, and progressives have a look of insanity that is like a neon sign. They usually dress strangely and have a crazy look in their eyes. There is kind of a hyena / weasel / snake thing about them. (in a figurative sense.) Hyenas, weasels, and snakes are wonderful creatures, but they have kind of become associated with certain unpleasant human traits. Blood thirsty, vicious, passive aggressive, dishonest, etc etc..... The ugliness inside of progressives works its way to their outward appearance, and they have a distinctive' wimpy demon' look that is unmistakable.
